LARN 136 C34D4

Start the following in class:

1.a. Write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper in your Journal notebook. In the upper right corner white space of each upward facing page, write your hand in number within a circle followed by your name. Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.

The first required focus topics, J136A, for today are

  1. In the physical sciences, does what does the term heat mean?
  2. In the physical sciences, what does the term thermal energy mean?
  3. In the physical sciences, what does the term temperature mean?
  4. Compare and contrast the terms endothermic reaction and exothermic reaction.
  5. How does one determine whether a given chemical process is endothermic or exothermic?

1.b. The second required learning journal topic, J136B, for today is

The specific heat capacity of a material is the ratio of (the amount of thermal energy absorbed when a sample of material increases one kelvin in temperature) to (the mass of the material absorbing the energy).

  1. What are the units of specific heat capacity used by the authors of our textbook?
  2. What are the molar heat capacities of aluminum, copper, iron, and silver?  That is, what are the values and units of the four products of the specific heat capacities of aluminum, copper, iron, and silver times their respective molar masses?  Be sure to include the units of each measured quantity, to cancel all units that are both in a numerator and a denominator of multiplied ratios, and to label the resulting units of each calculated value.  Also circle and express the calculated result to the proper number of significant figures.  The specific heat capacities of aluminum, iron, and silver are given on page 508 of your text.  The specific heat capacity of copper is given on page 510 of your text as the result of doing Sample Problem 17.1.
  3. For question b above, the molar heat capacities of aluminum, copper, iron, and silver were calculated.  The four values are very close to one another. What is the average the values of the four molar heat capacities?  Don’t forget to label the average value with the units of molar heat capacity.
  4. Multiply the value of the ideal gas constant, R, [Given on p 426 in the text] times the whole number 3.  What is the percent discrepancy of the average molar heat capacity of the four metals from the value of 3R which you calculated?  Please round off the value of the percent discrepancy to the nearest percent.

2.a. Use the PQ5R or SQ5R method to prepare study guide for text section 17.1 on The Flow of Energy — Heat and Work or go to https://socratic.org/chemistry  to research the topics brought up in section 17.1 of your text.  Read section 17.1 in your chemistry text, pages 504 through 510, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 17 vocabulary list that was distributed as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.

2.b. After you have finished reading the assigned section of the chapter, answer the formative assessment questions and do some formative assessment problems to inform you about the degree of your comprehension and understanding.  Assessment questions are printed at the end of the section that you have just read.  Reflect on your answers to assure yourself that you have understood the major points in the section that you have just read.  Record your responses to questions that are challenging you, so that you can later review what you are learning.  If all problems seem easy to you, record the response to the problem that was least easy for you to answer.

Writing in blue or black ink, place your hand in number in a circle followed by your name in the upper right white space of a piece of three holed composition paper that hasn’t been written on.  Place the page reference for the problems to be considered to the left of the red marginal line on the first blue line.  Centered on the first blue line, write a descriptive title for the learning activity such as Section C1.4 Responses where C1.4 represents Chapter1.section4.  Before you write your response to each question or problem listed below, write its designation to the left of the red marginal line as listed below, followed by your response in ink to the right of the marginal line.

If solving the problem entails the use of multiplication or division, show your work by including a ? followed by the unit of the quantity you are solving for, an = sign, followed by the quantity given that has all or part of the dimensions of whatever quantity you are solving for, followed by mathematical operations on all labeled quantities, conversion ratios or comparison ratios that are used to obtain the sought for quantity.

  • Study Conceptual Problem 17.1 on page 507. Answer the questions and explain your reasoning for practice problems I17-1ab (In chapter 17, problem 1ab) and I17-2.
  • Study Sample Problem 17.1 on page 510. Be sure to include the units of each measured quantity, to cancel all units that are both in a numerator and a denominator of multiplied ratios, and to label the resulting units of each calculated value.   Also circle and express the calculated result to the proper number of significant figures.  Show your work including all comparison ratios for practice problems I17-3 (In chapter 17, problem 3) and I17-4.
  • In the Section Assessment 17.1 on page 510, read, analyze, describe and explain practice problems I17-5 (In chapter 17, problem 5), I17-6, I17-7, and I17-8; and read, analyze, and show your work including all comparison ratios for practice problems I17-9, I17-10, and I17-11.
  • After you have finished responding to the formative assessment questions and problems, check pages R96 and R97 of the text and check each of those problems that you can by writing in either a check mark (√) or a correction in green ink.  Write down any question that you still have so that you can ask about it in class.  In the margin of your notebook page, circle the number of formative assessment questions do not have a suggested response given and check your response with that of your classmates when you come to class.

Recommended for those who have time left in their 45 minute study period, but not required of all:

1.. Download and open the Unit Learning Objectives for Cornell Notes document, press and hold the CTRL key while typing F to bring up a search (find) box.  Type in Chapter 17 in the search box and then move your cursor into the text area to the right and click there to see the first page of objectives.   Consider each learning objective as you proceed through the chapter with the aim of being able to demonstrate your understanding and ability to apply the learnings.  For now, study and take Cornell notes on objectives 2 through 8.  

2. Download current ActivInspire unit flipchart by logging on to the MNSD Google Drive and selecting it from the Student Resources > ActivInspire  folder.  Generally the flipchart name will begin with a capital U to designate the chemistry unit of study and end in a relatively high version number following the v at the end of the flipchart’s title.  Download the flipchart on the Thermochemistry after clicking on the following link: Thermochemistry.  Click through the chart quickly and take Cornell notes on concepts pertaining to the learning objectives that you are studying.  At the end of your study, write a summary statement of what you learned.
